TROUBLESHOOTING
SYMPTOM POSSIBLE
CAUSES
WHO PERFORMS
CORRECTIVE ACTION
CORRECTIVE ACTION
1. Fireplace turns off and
will not turn on.
Fireplace has
overheated.
Homeowner The appliance is protected with a
safety device to prevent it from
overheating. If the fireplace should
overheat, a thermal switch will
disconnect power to the unit and
will not come back on without
being reset. Reset it by turning
the main power switch off and
waiting 5 minutes then turning it
back on.
2. Flame is fixed
(unmoving).
Wiring may be loose
or the flame motor
may be defective.
Qualified Service Technician Inspect all wiring for loose
connections. If the wire
connections are good, replace the
flame motor.
3. Dim or poorly visible
flame or log set and
ember is not glowing.
Light bulb(s) burnt out
or wiring is loose.
Homeowner Inspect all wiring for loose
connections and repair or replace
if necessary. Inspect light bulbs
and replace if necessary.
4. Flame sputters. Flame motor is
defective.
Qualified Service Technician Replace flame motor.
5. Remote control does not
work.
Low batteries.
Unit switch and/or
wall switch in “ON”
position.
Homeowner Replace AA batteries in remote
control. If problem persists, there
may have been a loss of power to
the unit as a possible result from a
power failure (i.e. breaker tripped).
Turn off main power on/off switch
(see Figure 4) and/or optional wall
switch (if applicable).
6. Circuit breaker trips or
fuse blows when the unit
is turned on.
Improper circuit
current rating.
Qualified Service Technician Check the house circuit to ensure
it is on a dedicated circuit with
proper Amp. rating. If the circuit
breaker continues to trip (or blown
fuses), inspect wiring for a loose
connection or a dead short. Repair
or replace wiring and/or
connectors as necessary.
